Abstract- This paper presents a comparative study of solar fed single phase symmetric and asymmetric multilevel inverters. The solar fed symmetric and asymmetric multilevel inverters is triggered by multi carrier sinusoidal pulse width modulation (SPWM) technique. The SPWM technique include Phase Disposition (PD) strategy, Phase Opposition Disposition (POD) strategy, and Alternate Phase Disposition (APOD) strategy. Performance like %Total Harmonic Distortion (%THD), fundamental RMS voltage (Vrms) and Crest Factor (CF) are evaluated and the comparison results are presented. Simulation were performed using MATLAB/SIMULINK. It is observed that APOD PWM strategy provides output with lower distortions and higher fundamental RMS voltage.
